PROCESS OF BLEACHING HAIR.

SPECIFICATION forming part of Letters Patent No. 442,297, dated December 9, 1890. Application filed July 16, 1889. Serial No. 317,745. (No specimens.)

To all whom it may concern:

Be it known that I, FREDERICK G. WISE- LOGEL, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in a Process of Treating Hair, Feathers, the, of which the following is a full, clear, and exact description, that will enable others to understand and use the same.

This process relates more especially to the washing, cleaning, and curing of hog-hair, whereby the same may be converted into a merchant-able article.

The same process maybe used, with a slight modification, in cleaning and renovating feathers, the.

On account of the peculiar nature of hoghair it has always been a very difficult mat ter to properly clean and cure the same so as to produce an article of some commercial value. The hair is first passed through a picker or other machine of a similar character and then subjected to a thorough washing in cold water. The hair is next washed in hot water and treated by adding a little lime to the water to remove the oil, ammonia, and other matter. This part of the process being completed, the hair is next placed in a suitable drying apparatus and a strong current of dry air impregnated with the fumes of burning sulphur forced through to thoroughly dry, disinfect, and bleach the same. The hair is finally again passed through a picker, and is then ready for market. If the hair were first washed in hot water, the coagulated blood and the cuticle matter adhering to the roots would be turned into a gluey substance, which could not afterward be easily removed. The hair would also have a tendency to mat together and could not be rendered inodorous, and therefore could have no commercial value. By first washing in cold water and afterward washing in hot water to which has been added a little lime all this is obviated, as that has the effect of removing such matter as would afterward cause trouble when subjecting the hair to the hot bath.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The process herein described of cleaning and curing hair, which consists in first thoroughly washing the same in cold water and afterward treating the hair to a bath of hot Water to which has been added a small quantity of lime,substantially as and for the purpose set forth.

2. The process herein described of cleaning and curing animal-hair. which consists in first thoroughly washing the same in cold water, next treating the hair to a bath of hot water to which has been added a small quantity of lime, and finally placing the hairin asuitable drying apparatus and forcing a strong current of dry sulphureted air through the same until the process of drying is completed, substantially as and for the purpose set forth.
